Diffused Blue 5mm LED (25 Pack)

High-Visibility 5mm Blue Diffused LEDs

Upgrade your prototyping kit and custom electronics builds with this 25-pack of premium 5mm blue diffused light emitting diodes. Engineered for exceptional optical uniformity and long-term operating reliability, these standard T-1 3/4 through-hole components feature a tinted, frosted blue epoxy lens that evenly scatters light across a broad 60-degree viewing angle. Unlike clear-lens LEDs that cast an intense, narrow spot beam, the diffused encapsulation creates a soft, consistent ambient glow that prevents eye strain while maintaining clear readability from off-axis angles, even under bright indoor lighting or ambient daylight conditions.

Technical Performance and Electrical Specifications

Constructed using advanced Indium Gallium Nitride (InGaN) semiconductor material, these high-efficiency diodes emit a vivid blue hue within a dominant wavelength range of 460nm to 470nm. Each LED operates with a forward voltage drop between 2.9V and 3.3V DC (3.1V typical) at a standard nominal drive current of 20mA. Delivering a luminous intensity rating of 800mcd to 1000mcd, these optical indicators strike an optimal balance between modest power draw and high-visibility signal output. They feature a maximum reverse voltage tolerance of 5V, a peak forward pulse current of 100mA, and an operating temperature envelope spanning -40 degrees Celsius to +85 degrees Celsius. These electrical parameters allow direct control from 3.3V and 5V microcontroller GPIO pins when integrated with standard current-limiting resistors, such as 100 ohm for 5V logic or 10 ohm to 22 ohm for 3.3V logic.

Prototyping and Application Use Cases

Designed with standard 2.54mm (0.1 inch) lead spacing, these through-hole LEDs feature silver-plated copper leads with an elongated anode for quick polarity identification. They drop effortlessly into standard solderless breadboards, perfboards, stripboards, and dual-layer printed circuit boards (PCBs). These components are ideally suited for status indicator lights, power rails, user interface feedback panels, custom audio VU meters, networking gear display arrays, and STEM educational kits. Whether building an Arduino status monitor, an ESP32 IoT node, a Raspberry Pi expansion hat, or a standalone synthesizer panel, this 25-pack provides reliable visual signaling and an extended operational lifespan exceeding 50,000 hours.
